Abstract
Destructive and beneficial insect populations were monitored in reduced- and conventional tillage systems for cotton and tobacco for 3 years in plots located on the Pee Dee Experiment Station, Dargan Farm, Darlington County, S.C. Seasonal insect populations on plants in the two tillage systems were not significantly different, but records of emergence from soil indicated more Heliothis spp. moths were found in reduced-tillage plots than in conventionally tilled plots. Yield records for the two crops showed no significant differences between the two tillage systems.
